Ancient History/Human Evolution/Paleolithic Age In the early Paleolithic period, from about 3 million years ago until 1 million years ago, the hominids from which we arose lived much like other animals: they hunted and gathered food from natural sources, and ate only the food that was immediately edible to a human digestive system.

If the Earth is 4.5 billion years old and humans have only been around for a few hundred thousand years, how do we know there have not been many more civilizations and species before us? The Universe is 13.7B years old. The Earth has not existed since the moment the Universe was created and is about 4.5B years old and is made out the debris of two previous generation of stars. Life on Earth started shortly after the temperatures cooled down, about 3.7B years ago. Up until 600M years ago, life was predominantly single-celled organisms. From 600M years until now, the variety of life that we see evolved. Humans started to separate from the rest of the great apes about 7M years ago and we became modern humans 200k years ago.

450 Million Years of Sharks Life is thought to have begun on earth about 3.8 billion years ago. Life on earth began as bacteria and did not advance beyond the one-celled format until around 580 million years ago. The first fish appeared around 510 million years ago.These were armored jawless fishes known as ostracoderms.ammals first appeared around that same time. The first human-like animal, or hominid, dates to about 4.5 million years ago, but modern humans only date back perhaps 60,000 years. And recorded civilization has lasted only about 5,000 years.

- Scientific evidence says that the first modern humans, Homo sapiens, appeared more than 200,000 years ago. Some fossils from the middle Pleistocene period (about 400,000 years ago), referred to as Homo sapiens rhodesiensis, may be archaic Homo sapiens-a transitional species.

- We now know that the earth is approximately 4.54 billion years old and that there have been living things on our planet for at least 3.5 billion years. Modern methods of dating the earth and the major events in the evolution of life depend on understanding radioactive decay processes.

Earth 'will get too hot for humans' We had insects 400 million years ago, dinosaurs 300 million years ago and flowering plants 130 million years ago. Anatomically modern humans have only been around for the last 200,000 years-so you can see it takes a really long time for intelligent life to develop.

The possibility of profitable destabilizing speculation (PDS) affects the operation of competitive markets under uncertainty. For if speculators may profitably destabilize, then clearly real world markets can be unstable.n the opening paragraphs of this chapter we pointed out that speculation must be profitable over time, or the losses from speculative activity would be a self-correcting problem: the destabilizing speculators would fail to survive in a Darwinian sense.

How long have humans existed? Best Answer: It depends what you mean by human. The oldest evidence for the genus /Homo/ dates back something like 2.5 million years. The oldest remains of the species /Homo sapiens/ are perhaps 150,000 years old.

The oldest Homo sapiens Credit: John Fleagle, Stony Brook University. When the bones of two early humans were found in 1967 near Kibish, Ethiopia, they were thought to be 130,000 years old. A few years ago, researchers found 154,000- to 160,000-year-old human bones at Herto, Ethiopia. Now, a new study of the 1967 fossil site indicates the earliest known members of our species, Homo sapiens, roamed Africa about 195,000 years ago.

When did humans first step on the earth? The question is when? Years? Not where humans first step foot on the Earth. That is actually pretty ridiculous to say that humans have only been here for 6,000 years when we human fossils that are over 4.5 million years old and many religious traditions have records of people who have lived billions of years ago.

When Humans Became Human The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.

Human evolution Humans and the great apes (large apes) of Africa -- chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas -- share a common ancestor that lived between 8 and 6 million years ago. Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans. Scientists do not all agree, however, about how these species are related or which ones simply died out.

How Long Have Humans Been on Earth? Quick Answer. Modern humans have existed for roughly 200,000 years. The species to which humans belong, Homo sapiens, is the only species of human alive today. However, all species in the genus Homo are technically humans. This includes Homo habilis, the oldest undisputed species in the genus at 2.2 million years old.
